Does your data support your hypothesis?
Explain what seems to have happened; what did the rubber band do?
Explain at a molecular level what most substances do when heated and cooled.
Relate what happened in terms of entropy. (Hint: Look at the introduction again. Be sure to include something about temperature and entropy.)
What would you expect to happen to the temperature of a rubber band if you suddenly stretched it? (Try it!)
How about if you slowly stretched a rubber band and then suddenly let it contract?
Shrink- wrap uses heat (without melting it) to seal something in a special type of plastic. Explain how this must work.
What are the usual units of entropy?
Write a mathematical formula that includes entropy. Explain each of the terms in the formula.
